Detailed Description

Lightweight Stack Pool.

Handy class for pooling stacks of type T.

Usage:

• Claim a new stack using

  Stack<SomeClass> foo = StackPool<SomeClass>.Claim (); 

• Use it and do stuff with it
• Release it with

  StackPool<SomeClass>.Release (foo); 

You do not need to clear the stack before releasing it. After you have released a stack, you should never use it again.

Static constructor.

Member Function Documentation

static Stack<T> Claim ( )

static

Claim a stack.

Returns a pooled stack if any are in the pool. Otherwise it creates a new one. After usage, this stack should be released using the Release function (though not strictly necessary).

static void Clear ( )

static

Clears all pooled stacks of this type.

This is an O(n) operation, where n is the number of pooled stacks

static int GetSize ( )

static

Number of stacks of this type in the pool.

static void Release ( Stack< T >  stack )

static

Releases a stack.

After the stack has been released it should not be used anymore. Releasing a stack twice will cause an error.

static void Warmup ( int  count )

static

Makes sure the pool contains at least count pooled items.

This is good if you want to do all allocations at start.
